The` Schedule referred to in these Lettera Patent and making part of thesame To all whom 'it may concern Be it known that I, HENRY'GEBNER, ofthecity,

Y county, and State of New York, have inveuteda new and improved`Apparatus for Utilizing the Exhaust Steam of Steam-Engines; a'nd I dohereby declare the i followingtobe afull, clear, and' exact vdescriptionof the same, reference being. had to the accompanying ,drawingformingpart of this specification, in which steam-generator in such amanner that no portion otthe latent heat of the exhaust steam is lost,the said exhaust steam being mixed with the live steam in the receiverWhile `the water is pumped back into the generator, and by these means aVlarge percentage of heat generally wasted by allowing the exhaust steamto es- `cape in the atmosphere, or by condensing it in a condenser, issaved."

In the drawingp f The letter A designates a receiver, from the side ofwhich extends a pipe,.a, connected to a jet, b, which receives the watersaturated with'steam iiom alsteamgenerator, B, through a pipe, c.

p The jet is inclosed in an air-tightjacket, d, which 4 connects, bymeans of a pipe, e, with the exhaust-port of asteamfengine.`

vFrom the top part of the receiver extends a pipe, j, through which theengine is supplied'with steam, and another pipe, g, which extends'fromthe lower portion of the receiver, Vis connected to a pump, 7L, whichcommunicates, through a pipe,", with ,the steam-gener ator. p

, After steam of a suiiicient pressure has been raised in the generator,the stop-cock of pipe e is opened; and the water, saturatedwith steam,rushes through the jet into the receiver, `when the steam separates fromthewatcr, the steam being `taken to the engine.

The exhaust steam of the engine passes through the pipc'e into thejacket d, and is carried, by the action of the Vsteam jet, into thereceiver A, where it mingles with thelive steam and water, the wateraccumulating in the bottom part of the receiver being pumped back intothe steam-generator. i

During this process the latent heat, being disengaged from that portionof the exhaust steam which condenses, is not wasted, but it serves toincrease the heat, and, consequently, the pressure of 4 the noncondensed portion of the exhaust steam, enabling thesame to 'mingle withthe livesteam, and to be conducted back to the engine.

No heat is' wasted, therefore, in my apparatus, except what is lost byradiation or leakage, and the same water is used over and over again, sothat no supply of fresh water is required except what is needed to makeup l'or the loss by leakage, though it cannot be denied that a certainloss of power will result frpm the v Y operation of the-pump required toreturn the water to the generator; also, from the diminished tension ofthe steam employed for working the engine, and from the back pressurewhich will or may be caused by the ac-v tion of my apparatus on theexhaust steam, and the exact amount of gain resultingfrom my apparatus,or, in other words, thecorrectness of the'thcory set forth in theabove-description, canonly be determined by future experiments.

What I claim as new, aud desire'to secure by Letters Patent, is

The arrangement of a rceeiver,iinto which the exhaust steam from asteam-engiuejis driven by the action of a jet of live steam'and watertaken from a steam-generator, vand from which receiver steam is taken todrive the engine, while the water accumulating in the bottom partthereof is pumped back into the stcamgenerator, `al1 substantially inthe manner and for the purpose herein shown and described. v

rlhis specification signed by me this 7th day 'of April, 1S70.`
